Mozilla IT & Operations

We will have a scheduled downtime window this coming Tuesday from 7pm to 10pm PDT. The following changes will take place:

* 7pm PDT – NAS network settings changes. We will be updating network settings on our NAS. No expected downtime, but intermittent network filesystem access is possible through the window.
* 7pm PDT – Webtools migration. Bonsai, LXR and Tinderbox will be migrated to a new machine. 30-60 min of downtime is expected but could extend through the window.
* 8pm PDT – Updating firewall rules to internal networks. This will help improve network isolation and security. No expected downtime, but intermittent network connectivity is possible.
* 8pm PDT – SSH access to/from mecha will be disabled. If you use this host as a jumphost, you need an account on the new VPN server (announced multiple times).

Please let me know if you have any reason why we should not proceed with the planned maintenance. As always, we aim to keep downtime to as little as possible, but unexpected complications can arise causing longer downtime periods than expected. All systems should be operational by the end of the maintenance window. Feel free to email infra@mozilla.org if you see issues past the planned downtime.
